How Anisotropic Filtering Works?

Anisotropic filtering is a filtering technique used in 3D computer graphics in which the number of texture samples generated changes depending on the angle that the surface to be rendered is in relative to the camera.

Does anisotropic filtering increase FPS?

Anisotropic Filtering can increase and sharpen the quality of textures on surfaces that appear far away or at odd angles, such as road surfaces or trees. Anisotropic Filtering has a small performance cost (FPS) and can increase image quality in most 3D applications.

Should you use anisotropic filtering?

Trilinear filtering helps, but the ground still looks all blurry. This is why we use anisotropic filtering, which significantly improves texture quality at oblique angles. ... That's the area we should be sampling for this pixel, and in the form of a rough analogy, this is what anisotropic filtering takes into account.
